ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev. B | Page 6 of 36

Equivalent Digital Input Circuit Minimum Conversion Rate The clock rate at which the SNR of the lowest analog signal DEFINITIONS OF SPECIFICATIONS frequency drops by no more than 3 dB below the guaranteed Aperture Delay limit. Aperture delay is a measure of the sample-and-hold amplifier Offset Error (SHA) performance and is measured from the rising edge of the clock input to when the input signal is held for conversion. The major carry transition should occur for an analog value 1/2 LSB below VIN+ = VIN−. Zero error is defined as the deviation Aperture Jitter of the actual transition from that point. Aperture jitter is the variation in aperture delay for successive Out-of-Range Recovery Time samples and can be manifested as frequency-dependent noise on the input to the ADC.

If SENSE is grounded, the reference amplifier switch is connected to the internal resis- tor divider (see Figure 36), setting VREF to 1 V. Connecting the SENSE pin to the VREF pin switches the amplifier output to the SENSE pin, configuring the internal op amp circuit as a voltage follower and providing a 0.5 V reference output. If an external resistor divider is connected as shown in Figure 37, the switch is again set to the SENSE pin. This puts the reference amplifier in a noninverting mode with the VREF output defined as Rev. B | Page 17 of 36

AD9215 Data Sheet 0.05 Operational Mode Selection As discussed earlier, the AD9215 can output data in either offset 0 binary or twos complement format. There is also a provision for VREF = 0.5V enabling or disabling the clock duty cycle stabilizer (DCS). The R (%) –0.05 MODE pin is a multilevel input that controls the data format O and DCS state. For best ac performance, enabling the duty cycle R R –0.10 E stabilizer is recommended for all applications.
